The complete mitochondrial genome of the burrowing ghost shrimp, Nihonotrypaea harmandi (Bouvier, 1901), (Crustacea, Decapoda, Axiidea, Callianassidae) - a validation of the genus and species classifications.

ABSTRACT: The complete mitochondrial genome of the burrowing ghost shrimp Nihonotrypaea harmandi was reconstructed using the Illumina HiSeq platform. The genome was 15,272 bp in length made up of 37 mitochondrial genes (13 CDSs, 22 tRNAs, and 2 rRNAs) in the same order as other Nihonotrypaea species. Phylogenetic analyses suggested that Nihonotrypaea is a valid genus, and that N. harmandi can be phylogenetically marginally separated from N. japonica, though some authors considered the former as a synonym of the latter.

Project description:The genus Palaemon comprises worldwide marine and freshwater shrimps and prawns, and some of them are ecologically or commercially important species. Palaemon is not currently a monophyletic group, so phylogenetics and systematics are constantly changing. Species crypticism has been pointed out in several Palaemon species, being the clearest evidence in the European rockpool shrimp P. elegans. Here we sequenced and described seven European Palaemon mitochondrial genomes. The mitochondrial protein-coding genes were used, along with those of three other Palaemon species, to perform mitogenome phylogenetic analyses to clarify the evolutionary relationships within the genus, and particularly to shed light on the cryptic species found within P. elegans. The Messinian Salinity Crisis (5.3-5.9 Ma, late Miocene) was proposed to be the origin of this cryptic species and it was used as aged constraint for calibration analysis. We provide the largest and the first time-calibrated mitogenome phylogeny of the genus Palaemon and mitogenome substitution rate was estimated (1.59% per million years) in Decapoda for the first time. Our results highlighted the need for future systematics changes in Palaemon and crypticism in P. elegans was confirmed. Mitochondrial genome and cox1 (1.41%) substitution rate estimates matched those published elsewhere, arguing that the Messinian Salinity Crisis was a plausible event driving the split between P. elegans and its cryptic species. Molecular dating suggested that Pleistocene glaciations were likely involved in the differentiation between the Atlantic and Mediterranean populations of P. elegans. On the contrary, the divergence between the Atlantic and Mediterranean populations of the common littoral shrimp P. serratus was greater and dated to be much older (4.5-12.3 Ma, Plio-Miocene), so we considered that they could represent two separated species. Therefore, species crypticism in the genus Palaemon seems to be a common phenomenon.
